We do have a few activities set up.
with "Watch TV", it sometimes doesn't do anything, as the remote thinks things are on already. I suppose that if we used the remote 100% of the time for things it would work better.
We have a 19" sony TV with one RCA input. We use the input all the time (actually have a 4x switcher hooked up to it), so it usually stays on TV/VIDEO.
When I hit "Watch TV", it turns on the TV and reciever, sets the reciever to TV/DVD, but if the TV is still on TV/VIDEO, I have to go Devices --> Sony TV --> TV/VIDEO, when I could just get up and press the "TV/VIDEO" button that's about 4 feet away.
